Saving Eyesight worldwide
Vision loss is linked to socioeconomic disadvantage. Poor vision contributes to inequalities for marginalised and socially disadvantaged populations. 90% of people affected by eye diseases live in low- and middle- income countries. Sub-Saharan Africa is one of the worst-affected regions.
- 1.1 billion people globally have a vision impairment
- 43 million people are blind
- 90% of people with vision loss and blindness can be helped
Common causes of vision impairment and eye diseases
As the world’s most common cause of blindness, cataract has taken sight from more than 20 million people. Age, injury or genetics can cause the typical cloudy lens. Cataracts can be corrected with a simple 15-minute operation.
Glaucoma is another leading cause of blindness. Treatments include medication and operations. It is not possible to restore lost sight, but remaining sight can be preserved. Early detection is key!
Trachoma is the most common infectious cause of blindness worldwide. Repeated infections cause the inside of the eyelid to scar, making the eyelashes turn inward. These, in turn, scratch the cornea, leading to irreversible blindness. In the early stages, the disease is curable with antibiotics and preventable through improved hygiene. In the final stage, only eyelid surgery can prevent loss of sight.
Uncorrected Refractive Errors
153 million people live with a visual impairment, many due to uncorrected refractive errors. In most cases, a pair of glasses will allow them to see clearly again.
About 2 million children worldwide are blind and 12 million are visually impaired due to uncorrected visual impairment, vitamin A deficiency, cataracts, untreated infections or injuries.
